ACL Bearings 8B7281HX-STD Race Series Rod Bearing Set for Chevrolet Gen V 6.2L LT1/LT4/L86

The ACL Bearings 8B7281HX-STD is a high-performance connecting rod bearing set engineered specifically for Chevrolet Gen V 6.2L engines including LT1, LT4, and L86 applications. This Race Series bearing set features standard sizing with an additional 0.025mm (0.001") extra oil clearance, making it ideal for high-performance and racing applications requiring optimized bearing clearances.

Race Series Engineering Features:

• High-strength overlay plate with reduced thickness for improved fatigue resistance under extreme conditions
• Hardened steel backing on all rod bearings to enhance bearing lining support and retention in the housing
• Elimination of flash plating on bearing backs to maximize heat transfer and improve grip between bearing and housing
• Increased eccentricity to compensate for bore distortion at high RPM and assist hydrodynamic oil film formation
• Enlarged chamfers on both sides for improved fillet radii clearance with aftermarket crankshafts
• Precision-manufactured to tight wall thickness tolerances for consistent clearances
• Trimetal construction combining design, metallurgy, and engineering for championship-proven performance

ACL Race Series bearings are trusted by professional engine builders and have been standard components in record-setting race engines across NASCAR, IHRA, NHRA, and sport compact competitions. The standard width shells maintain OEM dimensions while providing the advanced materials and design features required for high-RPM racing applications.
